SANTA ROSA -- Agilent Technologies Inc. (NYSE: A) on Wednesday reported third-quarter revenues for its Santa Rosa-based Electronic Measurement Group decreased 17 percent.

Sales in the fiscal third quarter, ended July 31, were $701 million, compared with $845 million a year before.

In a report after stock-trading hours, the company attributed the group's sales dip to continuing weakness in wireless manufacturing.

The group's orders in the third quarter were $674 million, down 16.9 percent from $811 million last year. Operating margins for the group were strong at 18.5 percent, slightly higher than the Santa Clara-based company's overall margins of 18 percent.

The fourth quarter will be a continued challenge to the group, but no further adjustment of the workforce is planned, according to Guy Sene, group president. Agilent had companywide layoffs earlier in the year.

"That's behind us," he said.

"On a positive note, our employees here in Santa Rosa demonstrated their loyalty to the company by once again making us a winner in the Business Journal's Best Places to Work list," he added.

Mr. Sene pointed out that Agilent's three other business groups -- Life Sciences, Chemical Analysis and Diagnostocs and Genomics -- are showing gains from a year before, somewhat balancing the weakness in the Electronic Measurement group.

Agilent employs about 1,100 in Santa Rosa.

Companywide, third-quarter net sales were $1.65 billion, down 4 percent from a year before. Analysts had forecast sales of $1.64 billion.

Quarterly earnings were $163 million, or 49 cents per diluted share, down 31 percent.

The price of Agilent stock on Wednesday decreased 41 cents a share to $46.51, down less than 1 percent from the closing price Tuesday.

The price was up to $48 a share in after-hours trading.
